Sustainment

The two aspects of all this that are readily apparent are;
First, it isn't WHAT people do that is so damaging as the NUMBER of us doing it.
Secondly, we procreate as individuals but govern as a whole.
So, there will be lots of us are around to do collectively very damaging things with no control over the worlds population. This tends to point to a pyramid scheme of shortages of all sorts that Mother Nature will cruelly contain at a suffer ably awful level.
Why are we so intent on ignoring population in the equation(s)? We don't have to kill anyone at all; just manage things out into the future. It's simply the size of the can and what's in it, man.
